Ping
##################

You can find the Ping Tool at **Tools → Ping**.

The information is shown in real time in your browser.

With this tool you can test the reachability of a host.
It will send messages from this system to the destination which will be echoed back if it's reachable.

Enter the hostname or IP address of the destination and click on **Ping** to start.
You can specify the IP Protocol, v4 or v6, the **number of pings** and which **source** address shall be used, which uses auto by default.

A successful result could look like this:
::

Ping helps you in determining the reachability of a specific host/IP address. If you have a new rule configured that is supposed 
to block a specific website for example you can test the reachability (and thus the effectiveness of your rule) with ping. 
There is no need to actually visit the website to confirm that a rule is operational.
